HAND-OILER.

Application filed January 8, 1919.

To all whom it may concern:

Be it known that I, Bonn VIRGLL DAVIS, a I

citizen ofthe United States, residing at Rockford, in the county ofWinnebago and State of Illinois, have invented certain new and usefulImprovements in Hand-Oilers, of which the following is a specification.

This invention relates to hand oilers having force feed pumps, and theprimary object is to provide a generally improved oiler of this type,especially with regard to the construction and arrangement of the valvesand pump.

The average hand oiler of this character now on the market has little orno provision for conveniently cleaning the valves and oil passages,consequently when these oilers are used under certain conditions such aswith threshing machinery, mills, mining machinery, etc., they becomeclogged and inoperative in a comparatively short time and invariably,because of the lack of facility for cleaning, the oiler is rendereduseless and must be replaced by a new one. In the present invention Ihave provided a hand oiler of novel construction whereby the partssubject to clogging may be quickly and easily cleaned and put in thebest of working condition.

Another object resides in the provision of a pump arranged in suchrelation to the oil container or body as. to constitute the handletherefor and which shall be detachable to afford access to the valves.

A further object is to provide a valve structure and intake and feedtubing therefor so arranged as to afford quick and easy cleaning.

Referring to the drawing:.

Figure 1 is a vertical sectional view through a hand oiler embodying myimprovements;

Fig. 2, a plan sectional view taken on the line 22 of Fig. l; and

Fig. 3, a detail sectional view taken on the line 33 of Fig. 1.

The oil container proper may be of any suitable shape or size, and inthe present instance is of the usual shape given to oilers of thecharacter in mind. The container designated by character 5 carries theusual filling cap 6 and spout 7 A force-feed is employed for lifting theoil from the container 5 into the spout compartment and for forcing theoil from the spout in a fine stream.

My invention contemplates the provision of a pump so arranged as toconstitute the handle by which the container is carried. I have alsoprovided a novel valve arrangement including a valve casing in permanentrelation to the oil container and serving as a base upon which the pumpis detachably mounted. Thus the pump may be quickly removed at any timeafiording ready access to the valves. The valve-casing is furtherconstructed in such manner that the intake and feed tubes communicatingwith the oil container and spout respectively, are accessible forcleaning. In the present exemplification of my improvements, the valvecasing designated by character 8, is secured in permanent relation tothe container through the agency of the intake and feed tubes 9 and 11respectively. These tubes, it will be noted are secured in the valvecasing in spaced relation and in the present case constitute passagesextending entirely through the valve casing, which are closed at one endby screw caps 12. The tube 9 rigidly secured to the container 5terminates within the same at the bottom thereof and through this tubethe oil is drawn to the valve casing. The feed tube 11 also enters thecontainer 5 and directed upwardly, terminates within the spoutcompartment, it being noted that this compartment is separated from themain oil compartment of the container. The valve casing 8 houses a checkvalve '13 adapted to close the port 14 communicating with the intaketube 9 and also houses a springpressed check valve 15 normally closingthe port 16 between the cylinder and feed tube 11. The valve chambersare closed at their upper ends by threaded caps 17 having centralapertures or ports as shown.

The pump cylinder 18 is detachably fitted at its lower end to the valvecasing, and this connection may be effected in any suitable manner as bya threaded joint or a tapered wedge fit, the latter being shown in thepresent instance. A piston 19 disposed within the cylinder andconstantly urged upwardly by a contractile spring 21, is adapted to bepressed downward by means of a piston rod 22.

The upper end of the cylinder is held in operative relation to thecontainer 5 by means of a bracket or arm 23 fixed to and extendinglaterally from the container and having an opening 24 through which thecylinder is freely slidable. This bracket is also shaped to provide anupper curved portion 25 serving as 'a finger grasp.

In use, the operator carries the oiler by grasping the cylinder 18 whichmanifestly serves as a handle, the forefinger being inserted through theopening allorded by the bracket structure 2223. This leaves thethumbzfree.tomanipulatethe piston rod or plunger22'. By working thepiston, oil will rturewith a piston or pliuiger so arranged thattheoiler may be conveniently handled and manipulated. When for. any reasonit isidesired to clean the cylinder or the valve, the-cylinderanay bequicklyand easily de- 7 ,taohed. from the vv-alvecasing and withdrawnthroughithe opening-Ql. This exposes the top otfthevalve casing,permitting the caps 17-tobe .removed foraccess to the valves. Should thetubes 9 or 11 become clogged the screw caps ;12 111d,y be removed, thus.aflording immediate access to both tubes for cleaning either by means ofa wireor the like, or, by air or fluid under pressure. This constructionwhile comparatively simple, is well, adapted and thoroughly practicalfor the needs, of a hand oiler of this character and-will giveexceptional service under all conditions, because of the specialprovision for cleaning. In addition to these advantages the parts .aresoconstructed that the improvements may be produced at a comparativelylow cost.

While I have illustrated and described but a single embodiment of myimprovements, it shouldbe understood that changes might be made indetails of construction without departing from the spirit and scope ofthe invention as expressed in the appended claims, in which V r I claim:7

1. A hand oiler comprising a container having a spout, a feed tube andan intake tube emanating from the bottom portion of the. container, avalve. casing mounted on the ends oi said tubes and havingintake and.feed valves controlling the passages communicating with said tubes,anda cylinder pump detachablymounted on the valve casing and serving asa handle fortheoiler. V 2. A hand oiler comprising a container havi'ngaspout, intake and feed tubesemanating from the lower portion of thecontainer, a valve casing mounted on the ends of said tubes at theexterior of the container, a pump mounted ,on the valve casing, andremovable stops closing the ends of the tubes and pern'iitting accessthereto for cleaning. 7

3. In a hand oiler of the. character described, the combinationof acontainer having a delivery spout, a valve casinghaving horizontallyspaced intake and delivery valves, means supporting the casing in spacedrelation from the container and having associated therewith a passagebetween the'intake valve and the container and another passage betweenthe delivery valve and the spout, a cylinder pump detachably supportedon said valve casing and with both of said valves communicating with theinterior of the cylinder, and-means connecting the upper end of thecylinder pump with the container and permitting free removal of the pumpafter it is detached from said valve casing.
